Abstract
The invention discloses an intelligent device with screen locking and unlocking functions and an unlocking method thereof. The intelligent device comprises a main control processor, a display device, a wireless communication interface, a USB interface, an input device, a storage device, a fingerprint registering device and a fingerprint database. A screen can be unlocked due to the fact that the intelligent device can be flexibly selected according to fingerprint information of users or inputted codes, and safety and usability of the intelligent device are improved.
Description
Technical field
The present invention relates to a kind of hand-held intelligent equipment and unlock method thereof with screen locking function, especially a kind of have use finger print information to carry out hand-held intelligent equipment and the unlock method thereof of unlocking screen function.
Background technology
Along with the develop rapidly of electronics and communication technology, smart machine, particularly as the equipment such as panel computer and 3G smart mobile phone are widely universal.This type of smart machine not only can complete common voice and text communication function, and it can also complete the new business such as financing, stock, banking.The important personal information retaining on smart machine more increases.Therefore, the security of smart machine, integrity problem become increasingly conspicuous.
On the other hand, smart machine fast operation, multithreading multitask work, screen size are generally larger, thereby its power consumption is large, because battery capacity is limited, thereby is subject to larger impact service time.In order to extend working time, existing smart machine generally all has automatic screen lock function, and user being detected, without operating, duration surpasses certain hour or user presses after a certain screen locking button, enters lock state of screen to save the use of electric weight.
Generally in prior art adopt following two kinds of modes to carry out release to the smart machine under lock state of screen, the single pattern under first slip screen lock state (as laterally/longitudinal sliding motion one release stick or according to the standardized circle of screen prompt etc.) is with removing screen locking.Another kind of conventional unlocking manner is, according to user's setting, shows one group of out of order release pattern on screen, and each pattern that slides, puts into correct position by each pattern, only has all pattern position correct, and screen could release.In existing two kinds of modes, mode one lacks security mechanism, thereby anyone can enter system by unlock screen.Although mode two has certain confidentiality, user need to remember pattern, if forget arranged in patterns mode, validated user also cannot removing screen locking.
Summary of the invention
For two kinds of defects that unlocking manner exists in prior art, the present invention proposes unlocking screen method and smart machine that a kind of use biological information (fingerprint) and Password Input combine, use finger print information not need user's memory cipher, and other validated users of password have been obtained, also can lock by the mode contact screen of input password, thereby make this smart machine have security and ease for use concurrently.
The object of the invention is by realizing by the following technical solutions:
A smart machine with screen locking and unlocking function, comprising:
Main control processor, display device, wireless communication interface, USB interface, input media and memory storage, described display device that can screen locking is connected with described main control processor, the described wireless communication interface for 3G/2G/WIFI communication is connected with main control processor, described and external unit carry out data communication and are connected with main control processor for the USB interface to smart machine charging, the described input media that can be used for inputting unlocking pin is connected with described main control processor, it is characterized in that:
Described smart machine also comprises fingerprint input device and the fingerprint database being connected with described main control processor.

Further, described display device is the touch display screen with touch-input function.
Further, described input media, described USB interface and described fingerprint input device are positioned at the same side of smart machine, to facilitate user's one-handed performance.
Further, described smart machine is panel computer or smart mobile phone.
The invention also discloses a kind of unlocking screen method being applied in described smart machine, comprise the steps:
Step 1: enter lock state of screen after system boot;
Step 2: user selects whether to carry out being unlocked by fingerprint, if select be, go to step 3, otherwise, go to step 4;
Step 3: the induction of described fingerprint input device has finger print information typing, and the fingerprint character code of extraction is sent into main control processor, this main control processor query fingerprints database noly has the fingerprint character code of coupling to exist to judge, if have, unlocking screen, enter system, if nothing is returned to step 1;
Step 4: user selects whether to carry out unlock password, if select be, enter step 5, if select noly, return to step 1;
Step 5: described main control processor receives user and inputs user cipher by input media, judges that whether password is correct, if correct, unlocking screen, enters system, if incorrect, returns to step 1.
Preferably, if described display device is the touch-screen with input function, in step 5, use touch-screen input password.
Preferably, described password is word, numeral and/or graphical passwords.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
Fig. 1 is the block diagram of smart machine of the present invention;
Fig. 2 is method flow schematic diagram of the present invention.
